sustainable technology

In theory, it seems silly to pay for light bulbs and electricity when natural sunlight is free, and now this eco-fantasy is becoming a real possibility. Developed by EcoNation and installed on the roof, Lightcatcher is a sun-tracking solar dome that uses a mirror and technology-based system to generate green energy, bring light indoors, and mitigate temperature fluctuations.

The sensors and motorized mirror and lenses harvest sunlight, reducing energy costs and environmental impact eight times more than solar panels, according to EcoNation. The company also claims that Lightcatcher can provide sufficient light for up to ten hours per day, using only 1-3% of roof surface area.

You may have heard last year that scientists began exploring the idea of spray-paintable solar cells, and now researchers at Sheffield University in England have made a breakthrough that could bring this green energy dream one step closer to reality.

The advance comes from the use of organometal halide perkovskite, a mineral/crystal, organic/metal hydra, which offers the potential to combine high-performing, mature solar cell technologies with organic photovoltaics that have a low embedded energy cost.
